Watch those videos repeatedly. Get those concepts drilled into your head and practice the motions in your living room. Just that small bit of effort will get you farther then the vast majority of beginners.

After doing that, go one time and see if you still feel the need for lessons. Some people simply need another set of trained eyes to tell them what they are doing wrong.

I personally went three times before ever seeing those videos and I was using all the wrong techniques. The next season, after watching those vids, I did better my first day then at any other time. And I was on more difficult terrain then ever.
